IMIEIROVElIDv SPRING- BED-BOTTOM.

The Schedule referred to in these Lettera Patent and making partei theSame.

To all persons to whom these presents shall come:

4Beit known that 'I, GmEoN B. RICHMOND, vof Charlestown, in the countyof Middlesex and State of Massachusetts, have invented certain new anduseful Improvements in Spring-Beds, and that the followingl is a fulland exact description ot' the same, reference being had to theaccompanying plate of drawings.

'.lhe present invention relates to that class of spring bedsin which theslats, at each end, are secured to a trarne' by and through a springconnection, the spring portion of which is ot' a spiral form7 andarranged ditachment to the slat.

In the accompanying plate of drawings my improvements in spring-beds areillustrated,

Figure 1 being a'central longitudinal section of a slat connected to aframe, in accordance with my invention.

Figure 2, a plan View of one end of the arrange` ment of slat springs,shown in iig. 1.'

Figure'7 a transverse vertical section in plane of linea x, fig. 1.

A, in the drawings, represents a frame, constructed yof parallel side,B, and end, C, rails.

l), slats arranged in parallel lines between side rails B, with theirends E connected to the end rails 0 by 'and through an arrangement andconstruction of parts, as follows:

Y a a, circular apertures, through thickness ot' slats D, one at eachend, which apertures are rimmed or turned out on both sides of the slat.

11, spiral orcoiled springs of \vire,.connected and joined'together byaloop,- b, vwhich is a continuation of the wire from the coils of lthetwo springs; opposite to'each other the wire, at'the two outer ends ofthe coils, being extended, terminating 1n a hook,.d,

by which they are hung and connected to flexible or leather pieces, f,connected, in. turn, through hooks,

g, fastened to and in the end rails CV ofthe frame.

The loops b to the springs are. made with a curve l'in the direction oftheir lengtll,'a`nd by them, connectionis made with the slats, the loopsbeing inserted in their holes a, extending toward their center, restingupon the upper surface, h, and bearing against the' bevel or incline loftheraperture, both of the upper and lower sides ofthe slat, butat pointsdiametricallyy opposite, (see iig.- 1` more. particularly,) the coiled,springsbeingdirectly under the slat, with the slat resting thereon.

With slats hung to springs in the manner described, the greaterfthepressure on the slats the more the springs will be coiled, and thefirmer the fastening together of the slat and springs will be made, theloops being held to the slats by the bearing of the loop on its upper'side, and its bearing within the aperture against its incline, bothlupper and lower.

Having thus described my invention, lVbat I claim, and desire to secureby Letters Iatent, is-

The spring, consisting ofa continuous wire, doubly coiled at F, andextended beyond the coils into loop b, forming the upper termination ofthe spring, and entering an opening in the slat, in connection with/ theends oi' the wire below the coils, being connected to a piece j, asherein set forth.

The above specification of my invention signed by me this 2] st day ofApril, A. D, 1870. GIDEON B. RICHMOND.
